A. BARNA SHOE LAST July 7, 1931.

I Filed May 2, 1950 auveuto'c Wat @M Patented July 7, 1931 PATENT OFFICE.AIVDR'ENI BARNA, OF ASTORIA, NEW YORK SHOE-LAST Application filed May2,

This invention relatesto lasts used by makers and repairers of shoes.Usually the repairers of shoes as well as the makers provide themselveswith different sizes. of lasts a for different sizes of shoes withconsequent expense which is heavy, especially for the ordinary repairer,who sometimes seek to reduce this expense by applying to a last a pieceof leather or other material for the purpose of increasing the width orthe length as the case may be. Such devices, however, are unsatisfactoryin use and often lost. It is the object of this invention to provide adevice which can be applied readily to a last of given size and willremain alwaysin position and can be adjusted readily to increase thelength or width as the case may be. The invention will be more fullyexplained hereinafter with reference to the accompanying drawings inwhich it is illustrated, and in which:

Figure 1 is a view partly in elevation and partly in longitudinalsection of a last of usual construction but with the improved deviceapplied thereto.

Figure 2 is a view of the same in front elevation.

Figure 3 is a view similar to Figure 1, but.

showing the block in a different position.

The last many be made of wood or other suitable material and, forconvenience in use, may be formed with a main part a and a separableblock b, the latter being shown as detachably secured to the body a by afixed pin 0 and a spring supported pin d which can be pressed back torelease the block by the introduction of a suitable implement through ahole Z2 the spring supported pin cl yielding as the parts of the lastare brought together and snapping into the hole 6 as the block isbrought into position, all as usual in lasts of the character indicated.

The adjustable device or seam-piece may be applied to the last at onepoint or another 5 according to the form of the last and the re- 1930.Serial No. 449,183.

sult to be accomplished. In such a last as that shown in the drawings itis preferably applied to the block 7) near its forward end where theforward end of the device will be held by the upper against the last andwhere the adjustment of the device will provide for the desired increasein width or cross-sectional area. Obviously, the device may be applied,for example, to the heel when it is desired to provide for increase inlength.

In the embodiment of the invention shown the device comprises a plate eof metal, shaped to conform substantially to the surface of the last.This plate is preferably slotted longitudinally, as at 0 to receive aheaded and shouldered screw f, the shank f of which, between the head fand the shoulder 7, is of such size as to enter freely a slot 6 so thatthe plate is capable of movement with respect to the screw. The screw isreceived in a threaded tube 9 which is driven tightly into a hole 6bored in the last. When the screw f is turned home the plate e liessnugly against the surface of the last, but when the screw is turned outthe plate is carried away from the surface of the last to a positiondetermined by the width or cross-sectional area to be given to the shoe.The forward end of the plate may be engaged under the upper of the shoeso that it will be held upon or toward the surface of the last duringadjustment and so that the plate will be tilted somewhat as shown in thedrawings.

The mode of use of the device will be readily understood without furtherexplanation and it will also be understood that the form of the devicemay be Varied to suit different conditions of use.

I claim as my invention:

1. The combination with a shoe-last of a threaded tube set into thelast, a shouldered and headed screw engaged with the tube, and a plateshaped to conform substantially to the surface of the last and engaged90 freel} between the head and shoulder of the screw.

2. The combination with a shoe-last of a threaded tube set into thelast, a shouldered 5 and headed screw engaged with the tube, and a plateshaped to conform substantially to the surface of the last and engagedvfreely between the head and shoulder of the screw, the plate beingslotted longitudinally for 10 engagement with the screw.

This specification signed this 25th day of April A. D. 1930.

ANDREW BARNA.
